In the present study, application of porous acidic catalyst functionalized with an imidazole
ionic liquid ([SBA-Im]HSO4) as a phase transfer catalyst for the facile preparation of benzyl
thiocyanates and azides in water has been described. The catalyst has been characterized by
Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission
electron microscopy (TEM), thermogravimetric analysis (TGA) and derivative thermogravimetric
analysis (DTG). The polymeric phase transfer catalyst, easily recovered by simple
filtration, shows no appreciable loss of activity when recycled several times.
